problems registering

my friend tried to register on my forum but it said the "administartors have forbidden any new members" i went to the admin panel/users and groups/user options, and it says that new members are allowed to join. can any one tell me no one can register

Hi , Go into your Admin Panel=> General=> Forum => Configurations and make sure you dont have "Forum on Holiday" or "Forum in construction" clicked, that might resolve this problem.
